Abstract
In a fuel cell system having a fuel cell and a catalytic burner connected downstream thereof, an additional hydrogen-containing medium is fed to the catalytic burner.
Claims14
A fuel cell system comprising:
- at least one fuel cell;
- at least one catalytic burner connected downstream of the fuel cell and coupled to receive media which have been discharged from the fuel cell;
- and
- a feed device for feeding an additional hydrogen-containing medium to the catalytic burner during a start-up phase of the fuel cell system.

A fuel cell system comprising:
- at least one fuel cell;
- at least one catalytic burner connected downstream of the fuel cell and coupled to receive media which have been discharged from the fuel cell;
- and
- a feed device for feeding an additional hydrogen-containing medium to the catalytic burner;

- means for increasing the temperature of the catalytic burner, arranged in the catalytic burner.
3 more elements
A method for operating a fuel cell system having at least one fuel cell, and at least one catalytic burner which is connected downstream of the fuel cell, and is coupled to receive media which have been discharged from the fuel cell, said method comprising:
- feeding an additional hydrogen-containing medium to the catalytic burner;
- wherein the additional hydrogen-containing medium is fed during a start-up phase of the fuel cell system.
A fuel cell system comprising:
- a fuel cell;
- a catalytic burner coupled to receive a hydrogen containing media flow output from said fuel cell;
- a feed device for injecting an additional hydrogen containing medium into said catalytic burner;
- and
- a control unit for controlling an amount of said additional hydrogen containing medium injected by said feed device, as a function of one of a temperature of said catalytic burner, and time.
